To use PHP's cURL support you must also compile PHP --with-curl[=DIR] where DIR is the
location of the directory containing the lib and include
directories. In the "include" directory there should be a folder
named "curl" which should contain the easy.h and
curl.h files. There should be a file named
libcurl.a located in the "lib" directory. Beginning
with PHP 4.3.0 you can configure PHP to use cURL for URL streams
--with-curlwrappers.
Note:
Note to Win32 Users
In order to enable this module on a Windows environment,
libeay32.dll and ssleay32.dll
must be present in your PATH.
You don't need libcurl.dll from the cURL site.
